I sent an email to Lipotrim and this is what I recieved back in January. " In addiction to the water used to mix your diet, you must drink at least four pints of water each day - drink more if possible. See your carrier bag for information on how to make up the Lipotrim formula and for the list of permitted drinks. The foods we normally eat are made up of large amount of water. You will not be getting an adequate amount of water unless you purposefully drink it. It is advisable to drink a glass of water before and after each Lipotrim serving. Drinking should be frequent throughout the day, not all at once."
